How To Fix Pitted Cement Garage Floor

A pitted cement garage floor can be an eyesore and a safety hazard. The pits can trap dirt and debris, making the floor difficult to clean. They can also be a tripping hazard, especially for children and older adults. Fortunately, fixing a pitted cement garage floor is a relatively simple DIY project that can be completed in a weekend.

Step One: Preparing the Surface

Before you begin repairing the pits, you need to prepare the surface of the garage floor. This involves cleaning the floor thoroughly to remove any dirt, oil, or grease. You can use a pressure washer or a broom and a stiff brush to clean the floor. Once the floor is clean, you should allow it to dry completely.

Next, you need to inspect the floor for any loose or flaking concrete. Use a hammer or chisel to remove any loose pieces of concrete. This will ensure that the repair material will adhere properly to the floor.

Step Two: Filling the Pits

Once the surface is prepared, you can start filling the pits. There are a few different options for filling pits in a cement floor. One popular option is to use a patching compound. This is a self-leveling compound that can be applied to the pits and will create a smooth surface. Another option is to use concrete patch. This is a more traditional option that involves mixing concrete and applying it to the pits with a trowel.

Regardless of which method you choose, it is important to follow the manufacturer's instructions carefully. Make sure to pack the compound or concrete tightly into the pit. If possible, try to slightly overfill the pits. You will smooth out any excess material after the patching has had a chance to cure.

Step Three: Smoothing the Surface

After the patching compound or concrete has been applied, you will need to smooth the surface. You can use a trowel or a putty knife to create a smooth surface. This step is important because it will help to ensure that the repaired floor is even and level.

When smoothing the surface, be sure to feather the edges of the patching material. This means blending the patching material seamlessly into the surrounding concrete. Feathering the edges will help to avoid creating a visible line between the new patching material and the existing concrete.

Step Four: Curing and Sealing

Once the surface has been smoothed, allow the patching material to cure completely. This usually takes 24 to 48 hours. You can then apply a sealant to the floor. This will help to protect the floor from stains, spills, and wear and tear. A sealant will also help to make the floor easier to clean.

There are several different types of sealants available, but a polyurea sealant is a good option for garage floors. Polyurea sealant is very durable and can withstand heavy traffic. It also offers excellent resistance to chemicals and stains.

By following these steps, you can fix a pitted cement garage floor and create a smooth, durable surface that will last for years to come.
